Specification of Letters Patent. 1 Patient-cad June TS, TQ'Tfi,

Application filed April 27, 1917. Serial No. 164L834.

To all whom it may concern:

Be it known that we, LEONARD ALBERT HINDLEY, HAROLD DOUGLAS HINDLEY, and VVILLIAM STANFORD, subjects of the King of England, all residing in Bourton, Dorsetshire, England, have invented certain new and useful v Improvements in the Mannfacture of Horseshoes, of which the following is a specification.

This invention relates to the manufacture of horse-shoes and provides an improved process therefor, together with means for carrying out the said process. The means provided by the present invention take the form of an improved construction of machine of the kind in which the stock. is turned by being bent around a core-pattern by means of a wiper.

It has heretofore been proposed to manufacture horseshoes by punching or rolling processes which formed in the material holes that were parallel to one another, and subsequently to cut the material thus pierced into lengths which were then bent to the usual shape. It is an object of the present invention to provide a process for the rapid and economical production of horseshoes, preferably in a single heating, from plain bar stock, and further, if desired, a process by which the holes shall. have the requisite inclination to one another.

The present invention, therefore, provides a process for making horseshoes consisting in (a) drilling the stock cold with round holes for nail-holes prior to being turned b) subsequently turning the stock whore 1y the round holes are made approximately oval and drifting the holes to their final shape after the stock has been turned.

The term turned above and herein em ployed is used to denote the operation of bending the stock to the curved shape of the horseshoe.

For carrying out the process according to our invention, a machine will now be described, whereby the process may be clearly understood.

In the accompanying drawings Figure 1 is a side elevation of a machine for carrying out the process referred to above;

Fig. 2 is a plan of the machine, and

tit?

to the form the interior of the finished horseshoe is desired to take. Extending up through the circular portion of the core, and approximately concentric with said portion, is a vertical spindle B. This spindle can slide up and down but does not rotate, and fast upon it is a plate B At the top of the spindle is another plate 13 whose periphery is provided with steps set at different angles for the purpose hereinafter described. Mounted to pivot in any convenient manner upon the spindle B is a lever C. This lever lies immediately beneath the plate 13 has a heel C and carries on its underside a roller C The heel G is so placed that when a horseshoe, such as is indicated at D, is in place around the core A and the lever C is in the position shown in Fig. 2', the heel will lie over that end of the horseshoe remote from the roller C and the roller will bear against the opposite end of the horseshoe.

An adjustable stop E is provided for the starting end of the shoe and a file-faced clamping-finger F is pivoted at F near to the stop. The clamping-finger is controlled by a spring F which always tends to move it away from the shoe, and a locking-lever G is provided, having an eccentric G whereby the finger can be forcibly pressed against the shoe.

To move the spindle B endwise, a lever li-Lpivoted at H extends through a slot B in the spindle and can be pressed downward against a spring-control when desired; the spring-control is not shown in the drawing.

Pivoted to the lever H at J is a bar J which carries two plungers J These plungers extend through the table A and lie beneath the position occupied by a shoe when in position around the core.

A shoe is formed as follows :-The stock is out to dead length and drilled cold for the nail-holes at the correct angles by means of jigs. It is then heated, and while hot is placed at the side of the core A with its end against the stop E. The lever G is then pulled over and thus immediately clamps the stock against the side of the core. A tap with a hammer drives the part to the rear of the piece F against the core. Alternatively, the piece F may be situated sufficiently to the left (as viewed in Fig. 2) to eifect this itself. When the stock is inserted in the machine the lever or wiper-bar C lies over on the opposite side of the core from that occupied by it in Fig. 2 so that the roller C will lie behind the stock as viewed in Fig. 2. The wiper-bar is now swung around clockwise to bring it to the position shown in Fig. 2. By this movement the stock is turned by the roller pressing against it and bending it around the core A When this movement is completed, the heel C of the wiper-bar projects over the starting end of the shoe and the roller bears against the finishing end and holds it firmly against the core. The lever H is then depressed whereby the wiper-bar is made to press upon the shoe-ends so as to hold the shoe in position while the holes are punched. The holes, which were circular when drilled, are now oval owing to the turning movement, and the holes are now drifted by placing one or more drifts against the steps provided on the periphery of the plate B These steps are set at such an angle as to engage the upper part of the drift and bring it to the correct angle at which the holes are to be struck. This having been done, a clip is formed on the shoe at D by hammering this portion and the plate B is provided' with a jaw clearly shown in Fig. 2, which can accommodate the tool for striking down the metal prior to forming the clip by hammering the metal so struck down against the side face of the table A. All these operations are carried out during the single heat as they can each be quickly effected and the shoe therefore has no time to 0001 before it is finished.

A'ssoon as these operations are completed,

' the lever H, wl1ich may be held down by a rack or other suitable means, is released so that it rises under its spring-control and thus releases the shoe; the lever G- is swung back to release the holding finger F, and if the shoe sticks on the core, the lever H may be slightly raised so that the plungers J push it upward off the core.

The adjustability of the stop E enables shoes of slightly longer length than is provided for by the core to be made if desired, while nevertheless insuring that the stock when wiped shall be correctly placed for the drifting of the holes and the forming of the clip; the finger F further operates to insure that the stock shall not be drawn away from the stop E during the wiping operation.

A prominent advantage in the process provided by this invention is having the holes properly inclined to the face of the shoe to give the right direction to the nails, and it will be readily seen that such inclination of the holes cannot be obtained if they are punched simultaneously with one another by a multiple punch, as has heretofore been proposed.

Vhat we claim as our invention and desire to secure by Letters Patent is 1. In a process for making horseshoes, the steps consisting in, drilling round nailholes in the cold stock, heating the stock, turning the same whereby the round holes are made approximately oval and in the same heat drifting the holes to their final shape, substantially as set forth.

2. In a process for making horseshoes, the following steps consisting in, forming in the stock while cold nailholes the throughway of which is inclined to the face of the stock at approximately the angles required in the finished article, heating the stock, turning the stock, and drifting the nail-holes formed while the stock was cold to their final shape, substantially as set forth.

In testimony whereof we have signed our names to this specification.
